GENERAL DESCRIPTION
This data sheet details the specific properties of the
PCD3755A, PCD3755E and PCD3755F. The devices
differ in their Port and Power-on-reset configurations.
References to ‘PCD3755x’ apply to all three types.
The devices are members of the PCD33xxA family of
microcontrollers.
The shared properties of the family are described in the
“PCD33xxA family” data sheet, which should be read in
conjunction with this publication.
The PCD3755A, PCD3755E and PCD3755F are
One-Time Programmable (OTP) microcontrollers
designed primarily for telephony applications.They include
an on-chip generator for dual tone multifrequency (DTMF),
modem and musical tones. In addition to dialling,
generated frequencies can be made available as square
waves (P1.7/MDY) for melody generation, providing ringer
operation.
The PCD3755A, PCD3755E and PCD3755F also
incorporate 128 bytes of EEPROM. The EEPROM can be
used for storing telephone numbers, particularly for
implementing redial functions.
The Power-on-reset circuitry is extra accurate to
accommodate parallel telephones and fax equipment.
The instruction set is similar to that of the MAB8048 and is
a sub-set of that listed in the
“PCD33xxA family” data
sheet.
